Introduction Climate change impacts – impact upon cycling conditions and infrastructure Infrastructure and climate change risks for Vic Primary impacts – impact upon cycling conditions Sensitivity of materials – implications for material selection Impacts upon buildings Investigation and planning for new and existing facilities What can we do? - Questions to ask Page 2
Climate change impacts upon cycling and infrastructure • Extreme Events • Degradation of Materials • Resource Demand
• Health Impacts • Long Term Impacts
April 2010, Prahran, Melbourne • Direct impacts to infrastructure assets and activities • Direct impacts upon public confidence and lifestyle
Infrastructure and climate change risk assessment for Victoria Currently infrastructure and facilities are designed based on past climate, not future climate. Significant risk to facilities, and its owners (investors) and operators. Assessed all infrastructure including: • Residential, commercial buildings, industrial and storage facilities • Transport, power, water and communications
Primary impacts upon cycling conditions and infrastructure (Slide from Climate Risk, Karl Mallon)

Planning for new facilities
Position and resilience in system Adjust design standards & guidelines Materials selection
Built in flexibility, mobility, protection Change in technologies & expectations
Ability to adapt later • Design Guidelines for Climate & Sustainability, Major Australian Port • Australian Standard for Adapting Infrastructure and Settlements to Climate Change Impacts
Planning for existing assets
Manage system weaknesses Adjusting maintenance regimes Reposition and protect
Accept loss and early renewal Performance expectations
Enable emergency response
Guidance for Climate Resilience for Infrastructure, AusAID
The AGIC Sustainability Ratings Scheme Infrastructure covered: • Civil engineering head works of industrial processes
• Airports • Ports and marinas • Roads and tunnels • Railways and bridges • Cycle and pedestrian pathways • Distribution grids • Telecommunication infrastructure
• Water and wastewater supply and treatment infrastructure
What can we do? Ask questions and share information with government, community and organisations • do they understand their risks and exposure? • Are they assessing risk profile at regional or specific site scale, on programs, budget and systems? • Are they considering supply chain impacts on services, water, access, emergency response, community and economy? • Are we and they using the best information available at the time?
